Accelerating radio astronomy imaging with RICK: a step towards SKA-Mid and SKA-Low
Giovanni Lacopo, Emanuele De Rubeis, Claudio Gheller +2
The data volumes generated by modern radio interferometers, such as the SKA precursors, present significant computational challenges for imaging pipelines. Addressing the need for…
Accelerating cosmological simulations on GPUs: a step towards sustainability and green-awareness
Giovanni Lacopo, Marius Daniel Lepinzan, David Goz +7
The increasing complexity and scale of cosmological N-body simulations, driven by astronomical surveys like Euclid, call for a paradigm shift towards more sustainable and energy-ef…
Accelerating cosmological simulations on GPUs: a portable approach using OpenMP
M. D. Lepinzan, G. Lacopo, D. Goz +5
In this work we present the porting to Graphics Processing Units (GPUs, using OpenMP target directives) and optimization of a key module within the cosmological {\pinocchio} code,…
Green computing toward SKA era with RICK
Giovanni Lacopo, Claudio Gheller, Emanuele De Rubeis +5
Square Kilometer Array is expected to generate hundreds of petabytes of data per year, two orders of magnitude more than current radio interferometers. Data processing at this scal…
Accelerating radio astronomy imaging with RICK
Emanuele De Rubeis, Giovanni Lacopo, Claudio Gheller +2
This paper presents an implementation of radio astronomy imaging algorithms on modern High Performance Computing (HPC) infrastructures, exploiting distributed memory parallelism an…
